GIS Based Sensitivity Evaluation of Soil Erosion in Ji'nan City
Soil erosion is limited by various factors.Guided by the Universal Soil Loss Equation and the unique geographic features of Ji'nan City
primary evaluation factors for the sensitivity of soil erosion in Ji'nan City are determined
including precipitation
terrain undulation
soil quality
and vegetation.Every single factor is extracted and its sensitivity of soil erosion is obtained with the support of GIS technology.The comprehensive evaluation is then completed based on the work.By using the spatial analysis of GIS
it is easy to find the area and spatial distribution of different sensitivity grades.The study provides a scientific basis for governments to make policies of soil and water conservation.
